5 State of California., have invented new and useful Improvements iin Gate-Operatingpression formed at the intersection of the Means, of which the following is a specifiarched portions of the rail and the other cation. wheel will be positioned adjacent the en This invention relates to a gate operating of the rail, as illustrated in Fig. 1.

means. Extending upwardly from tie hangers 7 lt is the object of this invention to proare Standards S and secured at its ends to vide a mechanism for openinghand closing the standards 8 and extending therebetween is a sprocket chain 9. The sprocket chain 9 is engaged by a sprocket wheel 10 fixed on a short shaft 11 journaled in a suitable bearing block carried by the beam 2. The shaft 11 is provided with a pinion which is engaged with and adapted to be driven by a @ear wheel 13 fixed to a second slidable gates by means of which the gate may be given a closing movement by manual power and automatically continue to its full closed position.

bject is to provide means by Another o which a slidable gate will be automatically moved to and be retained in its closed pon shaft 14 jour- 9,0 sition with means including a sprocket chain Billed in Suitable bearings carried by the carried by the gate and a gear mechanism beam 2.

` Mounted on the shaft 14 is a crank 15 operable on same whereby the gate may be given an opening movement.

rlhe invention is illustrated in ianying drawing, in which:

Figure 1 is a view in side elevation of the gate illustrating same in its closed position. Fig. 2 is a plan view of the operating mechanism as seen on the line 2-2 o Fig. 1. 3 is a view in elevation of the track end showing one of the gate hangers thereon. Fig. 4 is a detail in plan of the end portion of the track. Fig. 5 is a detail vertical Section on the line 5,5 of Fig. 5, partly in elevation.

More specifically, A indicates a fence of any suitable construction provided with a gate-way B and having a beam 2 extending horizontally above the gate opening and for a distance corresponding to the width of the gate opening to one side thereof. Supported on brackets 3 carried by the beam 2. is a track 4 comprising two arched sections having a length approximately equal to the i Oate 5. One of the arched sections of the rail 4 extends across the gateway B and the other extending in continuation from the gate-way of the beam 2.

which is connected to a lever 16 fulcrumed on an upright 17 supported on the beam 2; the connection between the crank 15 and the lever 16 comprising a rod 1S. rlhe outer end of the lever 16 is provided with a depending i 19 which passes through a suitable friction claw or catch 2O adapted to engage and hold the rope 19 to maintain the outer end of the lever 6 in its lowermost position in opposition to a weight 21 adjustably mounted on the opposite end of the lever.

1n the operation of the invention, when it is desired to open the gate 5 a pull is eX- crted on the rope 19 to rock the lever 16 and thereby operate through the rod 1S and crank 15 to revolve the gear wheel 13 and thereby rotate the pinion 12, shaft 11 and sprocket wheel 1 rhe rotation of the sprocket wheel 1() will operate by reason of its engagement with the sprocket chain E) to shift the gate v5 rearwardly', this movement is continued until the gate is fully opened. The shape of the rails 4 assists in bringing the gate to its fully opened position and in fully closing it.

On operating the lever 16 to open the gate the accomarchvis disposed midway of its length with the catch 2O will engage the rope o reequal gradual curving slopes leading to their tain the outer end of the lever 16 in its depoints of intersection and to their opposite pressed position with the crank 15 .disposed ends. in approximately a vertical position. o

Mounted to travel on the track 4 are trolclose the gate the catch 2O is released wherelev wheels 6 attached to hangers 7 connectupon the weight 21 will operate to restore ing with the ends of the gate 5', the lever 16 the trolley to its normal position and thereby depress the crank l5 to gear Wheel 13, sprocket lO in a reverse direction, thereby lvance toward its closed position; gravitating to its position after the trolley Wheels have passed the higher points of the arched rails 4.

W hat I claim is:`

l. r gate operating mechanism, comprising a track having two successive and continuous arched portions, a gate provided with trolleys mounted on said track, a hor'- zontally extending' sprocket chain ixedly secured to and carried by said gate, a sprocket Wheel meshing With said chain, and means for rotating said sprocket Wheel.

2. The combination of a horizontai beam,

Wheel mounted in said bearings adapted to engage said sprocket chain, and means `for 1n either direcdriving said sprocket Wheel cham and gate.,

a beam, a, track mounted thereon comprising two successive and continuous arched portions, and a gate provided with trolleys traveling on said track and spaced apart a distance equal to the length or' one arch, of a horizontally eX- tending sprocket chain carried by said gate and extending between the trolleys, a sprocket Wheel, a shaft on Which said sprocket Wheel is mounted, a pinion on said shaft, a gear Wheel meshing with said pinion, a rocking lever', and means whereby movement of the lever in either direction will perate to rotate the sprocket `Wheel which engages the sprocket chain.
